DPC-16-55

Overview

The DPC-16-55 is a laminated core power transformer from the DPC-16 series by Signal Transformer. It features single or dual primary windings and through-hole mounting. The unit provides a dielectric strength of 1500Vrms and operates with a Class B insulation rating. Electrical specifications include a parallel secondary voltage of 8V and a series secondary voltage of 16V, supporting a maximum output current of 110mA in parallel configuration and 55mA in series configuration.

Feature Summary

• Offers single or dual primary winding configurations for flexible input integration
• Provides high dielectric strength of 1500Vrms for enhanced safety isolation
• Utilizes Class B insulation rating suitable for standard thermal environments

Applications

• General purpose AC to DC power supply conversion
• Industrial control equipment power stages
• Consumer electronics internal power regulation

Procurement Notes

Verify that the specific part number matches the required electrical parameters, particularly the 8V/16V secondary split and corresponding current ratings. Confirm that the through-hole package style aligns with the target PCB layout. Ensure the Class B insulation rating meets the safety standards required for the final application environment.

Selection Notes

Select this component when a 1500Vrms isolation barrier is required between primary and secondary circuits. The dual primary design allows compatibility with both 115V and 230V input lines without rewinding. Consider the physical dimensions of the laminated core to ensure adequate clearance on the printed circuit board during assembly.

Part Context

This transformer belongs to the DPC-16 series, which covers power ratings from 1VA to 24VA. These units are designed as single-phase transformers for through-hole mounting. The series is engineered to convert standard mains voltages into lower AC voltages for downstream rectification and filtering stages in various electronic systems.

Replacement Considerations

Compatible substitutes within the same family include other DPC-16 variants with matching voltage and current ratings. Verify that any alternative maintains the 1500Vrms dielectric strength and Class B insulation class to ensure equivalent safety performance.
